HMT has presented X-Pure, a grey water recycling system that it says can provide up to 500 litres of usable water from 100 litres of fresh water, provided the water remains in the circuit. The system treats grey water in three filtration stages and distinguishes between drinking, washing and shower water. X-Pure operates on 12 or 24 volt direct current, filters can be changed without tools via quick connectors, and the housing is described as vibration-resistant and leak-protected. On the German market the system will initially be offered as a B2B product for motorhome manufacturers and conversion companies, not for individual retrofitting. HMT names camper vans, part- and fully integrated motorhomes and expedition vehicles as intended applications.
